Title: Fundamental study of ash formation and deposition: Effect of reducing stoichiometry. Quarterly report No. 1, 18 May 1993--30 June 1993

Abstract

This project is designed to examine the effects of combustion stoichiometry on the fundamental aspects of ash formation and ash deposit initiation. Technical objectives are: to identify the partitioning of inorganic coal constituents among vapor, submicron fume, and fly ash products generated during the combustion of pulverized coal; to identify and quantify the fundamental processes by which the transformations of minerals and organically-associated inorganic species occur, and; to incorporate the effects of combustion stoichiometry into an Engineering Model for Ash Formation. Specific accomplishments during this quarter are as follows: The Project Program Plan was prepared and the subcontractors were authorized to begin work in this program. Acquisition of pyrite and kaolinite minerals for use in synthetic char production was begun. A fragmentation submodel was completed and incorporated into the PSI Engineering Model for Ash Formation (EMAF) that was developed previously.
